sorta looks like the back end of some type of shrimp . Try to post a frontal view of the little critter.

Look like some kind of crab. See If you can get him out and get a better pic. Seems like most crabs like that are not good.

Looks like a crab to me (i don't know about a emerald crab but it could be.) If it is a emerald I like mine they are cool to watch.
Were do you get that rock? I think that we started about that some time and the only thing that I have got off my rocks are pods and a little worm thing. I wish my rocks would have had stuff like yours.

Looks like the back of an emerald crab to me - They are fun to watch, but in my little experience, the BIG ones like to eat mushroom corals
